BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention may relate to a labeling system for labeling containers and controlling the rotational movement of containers or vessels such as bottles and cans on a transport carousel.

2. Background Information

Such devices are used in particular in connection with labeling machines for containers, for example, bottles and cans. During the mechanical labeling process, the containers to be labeled may be transported by means of a conveyor device to the transport carousel of a labeling machine. In the peripheral area of the transport carousel, there may be rotationally mounted turntables, on each of which, by means of a descending centering device (also called a “bell”), a container may be fixed in position on the turntable. Around the transport carousel there may be one or more stationary labeling stations. There may also be a brushing station on the transport carousel, which brushing station may be used, for example, for spacing or affecting or regulating the movement of the containers or facilitating their movement. For the actual labeling process, the containers on the rotating transport carousel may be transported past the labeling station or stations, as the containers are simultaneously rotated by means of the turntable relative to the transport carousel in a defined sequence of rotational steps, to deliver and move the containers past the respective labeling stations and to apply the labels at a defined angular orientation and at a defined speed of rotation and angular velocity.

To control the rotation of the individual turntables relative to the transport carousel, attached to each turntable may be a cam follower guide device which, during the rotation of the transport carousel, may roll along a radial cam or control cam that may be essentially non-rotational with respect to the transport carousel and follows the pattern of this cam during the rotation of the transport carousel. On this stationary radial cam, the desired sequence of rotational movements may be specified by the shape of the radial cam. As a result of the rolling of the guide device, which has, for example, a cross-shaped arrangement of rollers attached non-rotationally to the bottom of the turntable, along the radial cam, the desired rotational movement may be transmitted by the guide device from the radial cam to the turntable.

The radial cam can be realized so that it is outboard with respect to the cross-shaped arrangement of rollers, so that the cross-shaped arrangement of rollers follows the shape of the inside surface of the radial cam.

A similar device of the known art is described in German Patent No. 33 07 662 C2, hereby incorporated by reference herein, for example, which relates to a labeling machine with an outboard radial cam.

The known art also includes a labeling machine designated “Contiroll” and manufactured by Krones AG, in which the outboard radial cam is divided into stationary segments, and one segment can be replaced or exchanged to vary the shape of the radial cam and thus the specified rotational movement of the turntable and to adapt it to the shape and size of the containers currently being processed in the vicinity of the labeling station.

Because during the operation of a labeling machine, different labeling stations are distributed over the periphery of the path of rotation of the turntables around the transport carousel to perform the different process steps, such as picking up the label, applying the glue, positioning the label on the container, pressing the label onto the container, etc. access to the transport carousel and the radial cam underneath it, or in any case access to the areas where labeling stations are located in proximity to the transport carousel, is either very difficult or essentially altogether impossible, it can be extremely difficult or altogether impossible to detach or remove segments of the radial cam. To replace the entire radial cam by replacing all the segments, it is therefore necessary to remove all of the labeling stations, so that the radial cam becomes accessible over its entire periphery. Such a removal process is labor-intensive, time-consuming and difficult and requires the machine to be shut down for a long time, if all or even some of the segments of the radial cam are to be replaced.

European Patent No. 0 547 427 B1, hereby incorporated by reference herein, describes a device to control the rotational movement of turntables, in which the outboard radial cam can be adjusted in the direction of rotation, to thereby make it possible to bring different radial cam shapes into the active area and into contact with the guide devices rolling past them, thereby making it possible to adapt the machine to different sizes of containers. On this device, therefore, the desired portion of the radial cam is brought into the active area as a result of the rotation. On the other hand, there are no replaceable radial cam segments, because the desired variability of the active radial cam shape is determined by the rotational setting of the radial cam.

OBJECT OF THE INVENTION

One possible object of the present invention may be to create a device to control the rotational movement of containers in which essentially any desired radial cam can be essentially quickly and easily installed and removed, in particular essentially without a requirement for any tools.

SUMMARY OF THE INVENTION

At least one possible embodiment of the present invention preferably teaches that the radial cam segments may be detachably held on a cam carrier, whereby the cam carrier can rotate with respect to the stationary frame around the axis of rotation of the transport carousel. There may also be an immobilization device, by means of which the radial cam carrier can be detachably fastened in place to essentially prevent rotations with regard to the axis of rotation of the transport carousel.

In other words, in at least one possible embodiment of the present invention, the cam carrier may rotate either clockwise or counterclockwise.

On the basis of this possible configuration of the present invention, to replace a radial cam, the cam carrier can be released from its immobilized position and thus rotated, so that the radial cam segment to be replaced may come to lie in an easily accessible position. Following the replacement of the radial cam segment, the cam carrier can be rotated farther, and an additional radial cam segment can be replaced if necessary. After the replacement of all the desired radial cam segments, the cam carrier may be rotated back into its starting position and may be secured by means of the immobilization device to essentially prevent rotation, so that the radial cam can be essentially guaranteed to remain stationary. In this manner, the radial cam can be modified or completely replaced if necessary without having to dismantle and remove other devices that are located around the transport carousel. This capability may significantly reduce the amount of time and labor required to replace a radial cam.

The above-discussed embodiments of the present invention will be described further hereinbelow with reference to the accompanying figures. When the word “invention” is used in this specification, the word “invention” includes “inventions”, that is, the plural of “invention”. By stating “invention”, Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention is explained in greater detail below with reference to one exemplary embodiment which is illustrated in the accompanying drawings.

FIGS. 1-3 show a cross section of the relevant portion of a labeling machine.

FIG. 1 is a cross section elevation view of the labeling machine of FIG. 2; and

FIG. 2 is a plan view of a labeling marking incorporating at least one embodiment of the present invention.

FIG. 3 is a duplicate of FIG. 1 with additional information.

DESCRIPTION OF THE PREFERRED EMBODIMENT

According to FIGS. 1 and 2, the labeling system or labeling machine 10 has a base plate 36 which is part of a stationary frame (not shown). In the base plate 36, a vertical drive shaft 2 is rotationally mounted by means of a plurality of ball bearings 14 (shown in FIG. 1). Attached to the lower portion of the drive shaft 2 is a drive gear wheel 11 (also shown in FIG. 1). The drive gear wheel 11 is driven in rotation by drive devices that are not shown.

FIG. 2 shows, for example, a brushing station 43 that may be used for spacing containers, for facilitating spacing containers on at least one conveyance arrangement 45 or on turntables 4, or for otherwise regulating or facilitaing movement of containers to, in, through, within, and/or out of the labeling system.

FIG. 3 is a duplicate of FIG. 1 with additional information. For example, according to FIG. 3, the cam carrier 1 may have a first hub 49, a second hub 49, or a first and second hub 49.

Firmly connected to the drive shaft 2 is a transport carousel 3. The transport carousel 3 has a plurality of turntables 4 that are located concentric to the axis of rotation 50 of the drive shaft 2 and are distributed around the periphery of the transport carousel 3. Each turntable 4 is connected with a cam follower guide device 5, which is realized so that it rolls along a radial cam 7 located outside the rotational path of the turntable 4. In the illustrated embodiment, the guide device 5 has a cross-shaped arrangement of rollers 46 that are connected with the axis of rotation of the turntable. The cross-shaped arrangement of rollers 46 is an arrangement of four rollers 46, the vertical axes of rotation of which lie at the corners of a square. However, other shapes of roller arrangements 46 are also possible as guide devices 5 that are in contact with the radial cam 7. The shape of the radial cam 7 determines the relative rotation of the guide device 5 with respect to the purely radial direction with regard to the axis of rotation of the drive shaft 2 and thus determines the relative rotation of the turntable 4 with regard to the transport carousel 3 as it rotates.

The radial cam 7, in at least one possible embodiment of the present invention, is essentially easy to change or replace so that it may become possible to execute different rotation programs, i.e., to effect different desired rotational movements during the circulation of a container on a turntable on the transport carousel. This change or replacement is facilitated by the fact that along the periphery of the radial cam 7, the radial cam 7 consists of a plurality of segments that can be detached from the cam carrier 1. For example, the segments of the radial cam 7 can be fastened to the cam carrier 1 by means of screws that are accessible from above. The cam carrier 1, in at least one possible embodiment of the present invention, is also mounted so that it can rotate with respect to the axis of rotation of the drive shaft 2, and namely in the illustrated exemplary embodiment by means of ball bearings 42, which are located on the outside of the bearing shell of the bearing of the drive shaft 2. By means of this rotatable mounting, it may be possible to bring the cam carrier 1 and thus the respective segment of the radial cam 7 to be replaced into essentially the most accessible position possible on the labeling machine, so that the segment in question of the radial cam 7 can be replaced essentially easily. Following the replacement of the segment, the cam carrier 1 can be rotated farther to continue the replacement of additional segments. After the replacement process has been completed, the cam carrier 1 is again essentially fixed in position relative to the base plate 36, so that the radial cam 7 is again held non-rotationally and thus in turn forms a stationary radial cam along which the guide devices 5 can roll.

In the illustrated exemplary embodiment, the immobilization device to fix the cam carrier 1 in position to prevent rotation is formed by a slot 47 that runs in the cam carrier 1 and a threaded peg or piece 32 that is fastened in the base plate 36. The slot 47 in the cam carrier 1 is concentric to the axis of rotation of the drive shaft 2 and extends over an angular range such that the desired rotations of the cam carrier 1 with respect to the base plate 36 can be executed. Generally, a rotation capability of less than 180 degrees is sufficient. The threaded piece 32 is fastened on its lower end that projects out of the base plate 36 to the base plate 36 by means of a screw 34. To achieve a friction-tight or essentially friction-tight immobilization of the cam carrier 1 with respect to the base plate 36, the cam carrier 1 can be fixed in position by a clamping lever 38, for example, which when tightened may essentially ensure contact between the cam carrier 1 and the threaded piece 32, and thus may fix the cam carrier 1 in position in a friction-tight or essentially friction-tight manner with respect to the stationary base plate 36. The cam carrier 1 is thus clamped to the threaded piece 32.

Naturally, in connection with this invention, other types of immobilization devices can also be used for the non-rotational immobilization of the cam carrier.
